Homework Help: Physics

Posted by Cass on Thursday, October 3, 2013 at 10:30pm.

A powerful motorcycle can produce an acceleration of 3.5 m/s2 while traveling at 90 km/h. At that speed the forces resisting motion, including friction and air resistance, total 400 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.)

a.)What force does the motorcycle exert backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 255 kg?
